About filter washing and drying
For environments where popcorn grease and such can contaminate the filters, Barco advises the client to purchase one extra set
of filters to cover drying time, as well as taking following extra precautions and instructions pertaining to filter cleaning and drying.
Cleansing agent
To clean sticky, greasy dust filters we suggest usage of Sodium carbonate crystals (Na
washing soda, soda crystals, or sal soda in the detergent section of stores) is widely used to effectively remove oil, grease, alcohol
stains ... The product itself is relatively safe, sodium carbonate is used in toothpastes and as a food additive (E500). Potential
Hazards are described in the section "Hazards", page 157.

This cleaning procedure assumes that the filters are already removed from the projector.
Take into account that the time needed to dry the dust filters may be 24 hours or more. For that, it's recom-
mended to have a second set of dust filters which can be used while cleaning the first set.
Necessary tools
• Bucket with hot water.
• Sodium carbonate, 30 gram (handful) per liter hot water.
How to wash and dry the dust filters?
1. Make a solution with a ratio of 30 gram (a handful) sodium carbonate to 1 liter hot water.
2. Soak the dust filters in the solution for 30 to 60 minutes. The grease should be dissolved after 1 hour.
3. If the dust filter is still clogged repeat this procedure from step 1.
4. Rinse the dust filters with clean water to flush all grease residue away.
5. Shake out all excess liquid by repeatedly swinging the filter to-and-fro in a centrifugal action.
6. Then allow the filters to dry thoroughly. Typically this can take up to 24h and more, depending on the drying conditions.
Note: Drying time of the dust filters can be up to 24h or more. Drying time can be shorter when being done in a well-ventilated
area.
To speed-up drying, allow the filter(s) to dry at 50°C max in a well ventilated room.
